What are Wireless Networking Networks:
In order to adequately understand the meaning of wireless networking, a definition of computer networking will be briefly discussed. Computer networking is generally concerned with communication occuring between computer systems and can be defined as the scientific and engineering discipline used to make this happen. Computer networks involve, at the least, two computers seperated by a short distance (e.g. via Bluetooth) or thousands of miles (e.g. via the Internet). Computer networking is therefore sometimes considered to be a form of telecommunications. Wireless networks can be referred to as telephone or computer networks that use specific technology as their carrier or physical layer.
Wireless networking is a process of providing a connection to a DSL service through a wireless router so as to provide a convenient way to connect a small number of wired and any number of wireless computers. This is beneficial because through the integration of wireless connections to these computers, sharing or exchanging multimedia information and data can be done without the hassle or nusance of cables. Communication between these two mediums is further enabled with the use of standard network protocols and any technology which does this performs wireless networking. Wireless LANS are the most popular for wireless networking and has fuelled emerging industries such as IEEE 802.11 offering solutions and applications in the impossible event of wireless networking.
Types of Wireless Networking
Two dominant types of wireless networking exist for use today. These include:
- Ad-Hoc or Peer to Peer Networking:this type of network of made up of a number of computers each with wireless networking interface cards so as to aid with direct communication among every wireless enabled computer. Printers and files are shared this way. Access to wired LAN resources is not enabled unless one of the computers acts as a bridge to the wired LAN using special software for the process of "bridging".
- Access Points: some wireless networks use access points (also referred to as base stations). Access points act as hubs as they provide connectivity for wireless computers. Wireless LANS are connected to wired LANS and hereby allowing access to LAN resources by wireless computers. These LAN resources can include existing Internet connectivity or file servers. Two kinds of access points exist namely dedicated hardware access points and software access points. Hardware access points include examples such as Apple's Airport Base Station and offers support for a number of wireless features. Software access points run according to the specifications of ad-hoc wireless networks and offer support for features not included in hardware solutions, but may also not include those wireless features required by the 802.11 standard.
The process of "roaming" is whereby computers go from one access point to another. A steady network is ensured with the imcorporation of hardware and software which can maintain steady network connections through the monitoring of the strengths of various access points, finding the one of best quality. A number of access points require security authentification with the use of a valid password in order to fundamentally initiate these. To achieve roaming, overlapping wireless connections need to developed and implemented for use.
